17 produced trees with smaller TCA in year 5 (2003) remained small through year 11 (2008). Trees on Mahaleb, W.10 and W.13 had the largest TCA, whereas trees on Gi.3, Edabriz, W.53, Gi.5 and Gi.7 had the smallest TCA. W.13 produced the most root suckers, followed by W.10. All the other rootstocks, including W.10, had a similar amount of root suckers by year 10. Mahaleb, Gi.6, W.10, and W.13 had the highest CY. Fruit size was

yield (CY) per tree reflected TCA, with the larger trees tending to have the highest CY, and the lowest cumulative yield efficiency (CYE). Trees on W.53 had the highest CYE, which was statistically similar to that for trees on Gi.5, W.72, Edabriz, and Gi.7. Fruit on W.53 were the smallest. All other rootstocks produced fruit of a similar size. Ontario tree mortality was only significant on W.53 (62%) (Table 4). Rootstocks that
